commit 9f172f6fbd243759c808d97bd83c95e49325b2c9

drm/i915: Call i915_perf_fini() on init_hw error unwind
We have to cleanup after i915_perf_init(), even on the error path, as it
passes a pointer into the module to the sysfs core. If we fail to
unregister the sysctl table, we leave a dangling pointer which then may
explode anytime later.
Fixes: 9f9b2792b6d3 ("drm/i915/perf: reuse timestamp frequency from device
info")

It's hard to be sure since it causes memcorruption and dies in various ways on
subsequent tests.</pre>
